Container Gardening: ID for the fibrous 'posts' that philodendron roots grow into

Does anyone know what that material is called? It's fibrous and dark brown, cut or molded into posts buried in the soil and sticking up, and various types of philodendrons will send support roots into it as they grow upwards. Thanks!

I just saw some at Calloway's Nursery here in the DFW area - in the houseplant section.

I used to see them at Home Depot in the houseplant section, so maybe they still carry them?

I don't remember seeing them for the last few years until yesterday. They're not just compressed "sticks" of fiber any more - they're made of some kind of netting over a bundle of what looks like coconut fiber.

Oh.. I know what you mean.. I see it all the time
it's I believe what you're refering to.. Tree Fern posts.. or as this catalog calls them tree fern totemshttp://shop.greenbarnorchid.com/category.sc?categoryId=8
